IMPRQVEMENT IN MowmG-MACHINES.

Specification forming part of Letters Patent No. 141,611, dated August5, 1873; application filed July 15, 1873.

To all whom it may concern:

Be it Yknown'that I, W. V. WALKER, of Dresserville, in the county ofCayuga and State of New York, have invented certain new and usefulImprovements in Harvesters; and I do hereby declare that the followingis a full, clear, and exact description thereof, reference being had tothe accompanying drawings and to the letters of reference markedthereon, which form a part of this specication.

My invention relates to that class of harvesters in which tworeciprocating knives are used running in opposite directions, one on topof the other 5 and the nature of my invention consists in theconstruction and arrangement of the devices for giving to the knives thereciprocating motion, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make andY use the saine, I will now proceed to describeits construction and operation,l referring to the annexed drawing, inwhich- Figure l is a perspectiveview of so much of a harvester as willillustrate my invention, and Fig. 2 is a section of the driving-wheelwhich operates the knives.`

A represents the inger-bar of a harvester, attached to a suitable frame,B, which is connected to the axle C. On each end of this axle is placeda wheel-one, D, of which is provided with a circumferential rim, E,extending inward, as shown in Fig. 2. On the inner side of this rim isformed a zigzag groove, a, by attaching flanges to form said groove,or'in any other suitable manner. G G represent the knives orcutter-bars, moving one upon the other on the finger-bar. From the innerend of each cutter-bar G extends a rod, I), inward toward the Wheel D.These rods pass through the ends of a lever, H,

which is pivoted in the center to the frame B or to an arm extendingfrom the same. The ends of the lever H are forked, and the rods b b arepivoted in the same. After passing through the forked ends of the leverH the rods extend to'the inner side of the rim E on the wheel D, andtheir extreme ends are bent into the zigzag groove a, and have rollersz' t' upon them to work in said groove.

It will readily be seen that, the lever H being of the proper length, asthe machine moves forward the knives or cutter-bars G G obtain areciprocating motion in opposite directions.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent', is-

The combination, with the two knives or cutter-bars G G, of the rods bb, lever H, rol1- ers t' t', and the zigzag groove a formed on theinside of a projecting rim on the drivin g-Wheel D, all substantially asand for the purposes herein set forth.

In testimony that I claim the foregoing as my own I alix my signature inpresence of two witnesses.

WILLIAM V. WALKER.
